Integral cast-in-place frame on-bridge rail connection structure and construction method
The invention discloses an integral cast-in-place frame on-bridge rail connection structure, which is used for realizing rail connection of a newly-built railway and an existing line on a bridge and comprises a frame beam of a cast-in-place structure, a cantilever post-pouring section and bridge piers. The cast-in-place frame beam is arranged between two adjacent bridge piers of the existing line, the width of the cast-in-place frame beam is larger than that of an original existing line bridge, and the cast-in-place frame beam is eccentrically arranged towards a newly-built railway on the outer side. The lower portion of the frame beam is reinforced through pile foundations, and the upper end face elevation is higher than the upper end face of the piers. The lower end face of the cantilever post-pouring section is supported on the top of the piers. A newly-built railway, an existing line and a turnout device are arranged above the frame beam and the cantilever post-cast section and the frame beam and the cantilever are used as a bridge of the newly-built railway and the existing line. According to the method, the problem of on-bridge rail connection is solved, the engineering cost can be greatly reduced, the construction period is shortened, and compared with a brand new method for designing and constructing turnout continuous beams to achieve on-bridge rail connection, the method has the advantages that construction is rapid and convenient, and the cost is remarkably reduced.
本发明公开了一种整体现浇框架桥上接轨结构，用于新建铁路与既有线在桥上实现接轨，其中：包括现浇结构的框架梁、悬臂后浇段、桥墩；现浇的框架梁设置在既有线相邻的两个桥墩之间，且其宽度大于原既有线桥梁的宽度，并向外侧的新建铁路偏心设置；框架梁的下部通过桩基加固，其上端面标高高于桥墩的上端面；悬臂后浇段的下端面支撑于桥墩的顶部；框架梁和悬臂后浇段的上方设置新建铁路、既有线及道岔装置，作为新建铁路与既有线的桥梁使用。本发明解决了桥上接轨问题，可以极大的降低工程造价，节省施工周期，其相较于全新设计施工道岔连续梁以实现桥上接轨的做法具有施工迅速方便、显著降低造价的优点。
